iPhone Analog & Power Systems Engineer

The iPhone Division is seeking a talented Analog u0026 Power Systems Engineer to join a creative and collaborative engineering team developing next-generation iPhone products. This individual contributor role spans a broad set of analog disciplines including power management subsystems wired and wireless charging and mixed-signal function blocks such as audio sensors and signal will be at the focal point of many cross-functional interactions with Apples internal hardware/software teams contract manufacturer teams and IC vendor teams across all stages of development. We expect familiarity with portable low-power consumer electronics and a passion for building high-quality high-volume products. Depending on your background your focus may span power architecture and PMICs charging systems and battery management or analog/mixed-signal circuit integration or all three.n

As an analog and power systems engineer you are expected to bridge analog circuit design and system-level architecture. This requires a solid understanding of mixed-signal building blocks (op-amps filters ADCs/DACs output drivers) power conversion topologies (switching regulators linear regulators switched capacitors) charging systems (wired and wireless) and low-power sensor interfaces. You should be comfortable addressing system-level challenges including power sequencing interference mitigation PCB layout thermal management and digital interface design.

Plan system and subsystem power/charging architecture including IO trees power policies and charging strategies (wired and wireless)nDraft and review IC datasheets and specifications; distill system requirements into IC definitionsnConduct IC design reviews and manage bug tracking throughout the full design cyclenDrive and participate in system-level discussions on power management charging battery management and analog subsystem integrationnParticipate in IP development schematic and layout reviewsnLead or assist in prototype bring-up hardware demonstration and lab debuggingnPerform bench verification of functional and parametric characteristics including automation scriptingnConduct signal characterization across power charging and analog signal domainsnProvide production test support manufacturing support and field issue resolutionn
